Description
Technical field
The invention belongs to the technical field of material of construction, refer to a kind of cold water instant dissolving type composite glue powder for building especially.
Background technology
At building field, usually use sand-cement slurry when carrying out sticking brick, in order to improve the cohesive strength between basic unit and ceramic tile layer, in sand-cement slurry, admixture accounts for 107 glue (polyvinyl formal) of cement quality 10-20% usually; These traditional adhesive for building major parts are liquid, are inconvenient to store and transport, and meanwhile, this kind of liquid glue, mostly containing objectionable impuritiess such as formaldehyde, can produce harm to the people producing, construct, use, be unfavorable for healthy, contaminate environment.
Along with the development of building energy conservation consumption-reducing technological, building adhisive powder becomes the requisite improving building materials adhesiveproperties, minimizing sand-cement slurry consumption, and is rapidly developed.Building Adhesive was all the liquid glue prepared with rubber powder in the past, but due to poor storage stability, transport inconvenience is eliminated; At present, building adhisive powder also progressively to the future development of pressed powder rubber powder, is directly watered use at the scene.But existing building adhisive powder is poorly soluble, dissolves slow, need auxiliary whipping device or warm water to dissolve, and the cohesive strength of gained glue is low, poor water resistance, seriously govern its application in building trade.
Summary of the invention
The invention provides a kind of cold water instant dissolving type composite glue powder for building, solve building adhisive powder in prior art dissolve slow, cohesive strength is low and the problem of poor water resistance.
One of the present invention cold water instant dissolving type for building composite glue powder, it is mainly realized by the following technical programs: be made up of the raw material of following parts by weight: pre-gelatinized Hydroxypropyl Tapioca Starch 40-60 part, pva powder 10-20 part, Vltra tears 5-10 part, methylcellulose gum 5-10 part, resin rubber powder 1-10 part, Calcium hydrogen carbonate 5-10 part, nano silicon 5-10 part, magnesium oxide powder 10-20 part, silica flour 5-10 part.
Preferably, be made up of the raw material of following parts by weight: pre-gelatinized Hydroxypropyl Tapioca Starch 50 parts, pva powder 15 parts, Vltra tears 8 parts, methylcellulose gum 7 parts, resin rubber powder 5 parts, Calcium hydrogen carbonate 7 parts, nano silicon 8 parts, magnesium oxide powder 15 parts, silica flour 8 parts.
The invention has the beneficial effects as follows: cold water instant dissolving type composite glue powder for building of the present invention can dissolve rapidly in cold water, easy construction, and viscosity is high, cohesive force is strong, nonpoisonous and tasteless; After this composite glue powder bonding, its bonding is firm, water-tolerant, long service life; It reaches the strong index specified in JC/T547-2005 " ceramic wall and floor bricks tackiness agent " standard in tile bonding performance test experiment, and, higher than the performance of existing commercially available building adhisive powder.Meanwhile, this composite glue powder is convenient to long-distance transport, convenient storage, and long quality-guarantee period, is widely used; Both can be used for producing glue, can be used for again producing putty powder, thermal insulation mortar etc., easy to use, with low cost, 1 kilogram of rubber powder can produce 50 kilograms of glue.
